Why are you just saying things you know isn't true?

This one shows that clang is superior to both gcc 4.2.1 and gcc 4.6.
I haven't test data now but a month or so ago I tested them on one of
the Alioth Shootout examples (nestedloop probably). gcc 4.2.1 was
winning, clang was close with fractions of percent drop of speed but gcc
4.6 was off for nearly 7%.
3) The continuously increasing trend of introducing 'non standard'
features,
No need to use them.
